Picking the right product

Thickness for the U-value

The thickness you need depends on the U-value the building regulations require and the rest of the build-up. Manufacturers publish U-value tables; your designer or building control will confirm.

Sealing joints

Tape the joints with foil tape so the foil layer works as a continuous vapour control layer where the design relies on it.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Quantities: a worked example

Insulating 20 m² of rafters, floor or wall takes 8 boards of 2400 × 1200 mm including offcuts. The thickness depends on the U-value you need, so check it before you order. Try the insulation calculator
